Abstract: A needle assembly has distal and proximal ends. The needle assembly comprises a body element having distal and proximal ends, an attachment means configured to be attached to a medication delivery device, a button element which is movable from a first position to a second position, and a needle configured to move to the distal direction, when the button element is moved from the first position to the second position.

Abstract: A medication delivery device (1) comprises an indicator element (3) having indications (300) and a magnifying device located over an indication position (32). The magnifying device (4) comprises an optical system (5) with a magnifying lens (43) wherein the optical system (5) is constructed such that the optical path length between the indication position (32) and the magnifying lens (43) is enlarged. As an example, the medication delivery device (1) is a pen-type device, wherein a dose dial element (30) having a dosage scale (31) is disposed. The magnifying device (4) generates a magnified image of the dosage scale (31) so that the size of the selected dose (33) of the medical product is visible through a window (41). A method for assembling the medication delivery device (1) includes providing a medication delivery device (1) having a receptacle and mounting an element of the magnifying device (4) at the receptacle.

Abstract: The present invention relates to a drug delivery device for dispensing of a predefined dose of a medicinal product, comprising: a housing, a cartridge holder adapted to receive a cartridge containing the medicinal product to be dispensed, the cartridge holder being connectable to the housing, a drive mechanism to be operably engaged with the cartridge for setting and/or dispensing of a predefined dose of the medicinal product, wherein the drive mechanism is axially slidingly supported in the housing for compensating axial clearance between the drive mechanism and the cartridge and wherein the drive mechanism is axially fixable relative to the housing.

Abstract: The present invention relates to a drive mechanism for a drug delivery device for dispensing of a dose of a medicinal product, comprising: a holder for a product-containing cartridge, the cartridge having a piston slidably arranged therein in an axial direction, a piston rod to be operably engaged with the cartridge's piston for dispensing of a dose of the medicinal product, an adjusting assembly adapted to eliminate axial clearance between the piston and the piston rod, wherein the adjusting assembly comprises at least one radially extending spike element for mutually locking in position the piston and the piston rod irrespective of the relative distance between piston and piston rod.

Abstract: A drug delivery device for dispensing of a dose of a medicinal product is presented comprising a first housing component having a receptacle being oval- or elliptically shaped in radial cross section and being adapted to at least partially receive an insert portion of a second housing component being at least partially insertable into said first housing component along an axial direction, wherein the insert portion is oval- or elliptically shaped in radial cross section. The outside dimension or an at least one outside diameter of the insert portion is at least in sections larger than a corresponding inner dimension or an at least one inner diameter of the receptacle and wherein the insert portion and the receptacle are adapted to generate a radially acting mutual clamping of first and second housing components in a pre-fixing assembly configuration.

Abstract: The present invention relates to a drug delivery device for dispensing of a dose of a medicinal product, comprising: a first housing component (12, 52; 62) adapted to receive a cartridge (16) comprising the medicinal product and further comprising a piston (18) slidably arranged therein in an axial direction, a second housing component (14; 54; 64) adapted to receive a dose dispensing mechanism having a piston rod (20) to be operably engaged with the cartridge's piston (18), wherein the first and the second housing components (12, 14; 52, 54; 62, 64) are displaceably arranged in axial direction relative to each other for reducing an axial distance (34) between the piston (18) and the piston rod (20) to a pre-defined degree, and an interlock means (30) adapted to interact with at least one of first and second housing components (12, 14; 52, 54; 62, 64) for mutually locking into position first and second housing components (12, 14; 52, 54; 62, 64).

Abstract: A drive mechanism (13) for a drug delivery device (1), comprising a housing (2), a transfer member (14), a drive member (16) and a piston rod (18). The transfer member (14) is configured to be rotated about a transfer member rotation axis (20) with respect to the housing (2) for delivering a dose of a drug (5). The drive member (16) is configured to be rotatable around a drive member rotation axis (39) with respect to the housing (2). The drive member (16) is arranged within the transfer member (14). When delivering the dose of the drug (5), the drive member (16) rotates about the drive member rotation axis (39).

Abstract: The present invention relates to a drive mechanism for a drug delivery device as well as to a drug delivery device for dispensing of a dose of a medicinal product, wherein the drive mechanism comprises: a holder for a product-containing cartridge, the cartridge having a piston slidably arranged therein in an axial direction, a piston rod to be operably engaged with the cartridge's piston for dispensing of a dose of the medicinal product, at least one adjusting member slidably arranged in axial direction relative to the piston and/or relative to the piston rod for eliminating axial clearance between the piston and the piston rod, an interlock means adapted to interact with the adjusting member for mutually locking in position the piston and the piston rod irrespective of the relative distance between piston and piston rod.
